Ambrosia beetles are considered one of the major causes of three mortality in forest ecosystems; however, in some cases, they could cause huge plant mortality even in fruit orchards. Ambrosia beetles are polyphagous insects, belonging to the order Coleoptera, family Curculionidae. Thus, they are able to attack both coniferous and broadleaved trees. In the last few years, a considerable increment of ambrosia beetle attacks (mainly Anisandrus dispar) has been observed on apple orchards in South Tyrol, Italy. Ambrosia beetles excavate galleries into apple trees, inoculating them with ambrosia fungi. Apple trees infested by adults and larvae of A. dispar show suffering symptoms. Often, there is a reduction of fruit production and in the worst case of heavy infestation, young trees rapidly decline and die suddenly just after flowering. Unfortunately, the use of insecticides are not effective in every case because the insect spends the majority of its life cycle into tree trunks. One of the main opportunity to reduce ambrosia beetles in apple orchards is the use of mass trapping, using specific traps. Our project is based on understanding the efficiency of two different traps: Rebell Rosso® and a recently developed funnel trap, using ethanol as insect attractor and water with soap as control for ambrosia beetles. The research is organized by using: four Rebell Rosso with ethanol and four Rebell Rosso with water and soap. Instead, for funnels traps, we are going to use two funnels with ethanol and two funnels with water and soap. This thesis project is done in collaboration with Dott. Manfred Wolf, Unit of Entomology of the Laimburg Research Centre.
